Description
Technical field
The present invention relates to a kind of cold punching device technical field, more particularly, to a kind of upper pressure type pressuring flat device.
Background technology
Usual in two ways to the reflexed of stamping parts at present, one is upper pressure type, and one is side-push, wherein,
Side compression type is divided into blanking, 90 ° of angles (flange) of folding, side and is bulldozed three steps, and upper pressure type is divided into blanking, 90 ° of folding
Angle (flange), pre-fold 45° angle and flatten four steps, the Tool Position Comparision of upper pressure type device is more, but reflexed pressure
Flat effect is good, although fewer the step of side-push, but product easily wrinkles, and quality is difficult to ensure that.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of upper pressure type is flattened
Device.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of upper pressure type pressuring flat device, for stamping parts reflexed to be flattened, described pressuring flat device includes work base station,
And it is arranged on the pressure flattened by the flange body of stamping parts flange and by the stamping parts after flange on work base station
Flattening mechanism, is additionally provided with the removable clamp system of fixed stamping parts on work base station, and described pressing mechanism includes
Flatten drift and drive and flatten the drive component that drift is pushed, described pressing drift includes pressed flat, the pressed flat
One end be downwardly protrude to form prevent stamping parts deform limiting section, also add at the undertaking of pressed flat and limiting section
Work has pre-folds bent angle in arc-shaped.The setting of limiting section can be avoided in stamping parts applanation process, flange position folding
Bending angle is not right, so that the problem of causing to flatten not in place.And pre-fold bent angle setting can during pushing,
The stamping parts after flange is enabled first to carry out the bending of certain angle, consequently facilitating pressed flat is flattened to it.
The one side of described limiting section towards stamping parts is inclined domatic to stamping parts.Domatic setting is easy to turn over
The flange position of stamping parts behind side along it is domatic, pre-fold bent angle, the direct of travel in the pressing face of pressed flat is gradually pressed
It is flat.
Described domatic inclination angle is 70 °~80 °.
Described flange body include flange component, the flange component include erection support, contiguous block, flange cylinder,
Swinging mounting and flange extrusion, described erection support are fixedly installed on work base station, described flange cylinder
It is fixedly installed on erection support, one end of described swinging mounting is rotated with erection support to be connected, and is set on the other end
There is a flange extrusion, one end of described contiguous block is articulated and connected the drive end of flange cylinder, the other end is articulated and connected
The middle part of swinging mounting.
Described flange extrusion is in spherical or cylindric.This shape flange extrusion is when extruding stamping parts, no
The flange position of easy damaged stamping parts, and then can guarantee that the quality that last reflexed is flattened.
Connection between flange cylinder, contiguous block, swinging mounting and flange extrusion, which is set, to be met：
When the drive end outreach of flange cylinder is maximum, the horizontal hunting amplitude of swinging mounting is maximum, and flange
Extrusion is just by stamping parts flange.
Described flange body also includes the flange block being connected with drive cylinder, and the flange block is squeezed towards flange
Casting die side is provided with vertical block face；
During work, what flange block compressed stamping parts and exposed stamping parts treats flange position, the extruding punching of flange extrusion
Casting die simultaneously makes the flange position for the treatment of of stamping parts fit vertical block face.
Described removable clamp system is included in the moveable platform moved on work base station and is arranged on removable
Clamp assembly on platform, the clamp assembly includes being arranged on two fixture blocks on moveable platform, two fixture blocks with it is removable
The mounting groove for placing and clamping stamping parts is formed between moving platform.
Two described fixture blocks are fastened on the clamping cylinder on moveable platform respectively, and drive tune by clamping cylinder
Save the size of mounting groove.
When clamping stamping parts, the depth of described mounting groove is matched with shape with the non-flange position of stamping parts.
During present invention work, fixed to clamp in the mounting groove that first stamping parts is placed on removable clamping mechanism,
And expose and treat flange position, then it is moved to flange working position.Flange operation is proceeded by, now, flange block
That pushes down stamping parts and expose stamping parts treats flange position, and flange component operation is extruded by flange extrusion and to treat
Flange position is gradually fitted the vertical block face of flange block, so that flange is realized at shape bending angle in 90 °.Flange is complete
Cheng Hou, flange component resets with flange block, and stamping parts is moved to pressing station again, and drive component is (under being
Air cylinder etc.) drive pressing drift to be flattened to the step punching press of stamping parts one in place, that is, the stamping parts after being flattened.
Compared with prior art, the present invention has advantages below：
(1) process is few, and production efficiency is high：Pressed flat, limiting section and bent angle is pre-folded in the pressing drift of the present invention
Setting, effectively by it is conventional flatten in process pre-bend and pressure head and flatten drift and combine so that former
The four steps pressing come only needs to three steps in place (to be mainly flange and flatten two steps), so as to be effectively reduced
Process, improves production efficiency, reduces cost.
(2) it is simple to operate, it is easy for installation：Flange component is by contiguous block, flange cylinder, swing in flange body
The part such as support and flange extrusion is constituted, for conventional flange tool, and swinging mounting driving flange is squeezed
The mode of casting die causes flange body to may be located on the same side of work base station, consequently facilitating installing and operative employee
The operation of people.
(3) each cylinder etc. can also be connected control by flange body and pressing mechanism with control system, then coordinate sense
Device is answered to repack the pattern produced automatically into rapidly.
